Definitions

  • This invention relates to connecting devices having a heat recoverable member. More particularly, this invention relates to heat recoverable connecting devices which have at least two members acting in concert such that the heat recoverable member provides a supplementary force for making strong electrical and physical connections.
  • connection methods have, until recently, largely depended upon traditional methods such as soldering and crimping to effect the connection of, for example, conductors and cable screens. Widely used connection methods also have included pin and socket connectors as well as nut and bolt connectors.
  • reusable devices In particular applications, it is necessary to employ reusable devices. While traditional pin and socket devices are generally considered to be reusable, the strength of the resulting physical and electrical connection is not sufficient for many applications.
  • a soldered connection typically provides sufficient electrical continuity, however it is often not reusable because of its physical location or the heat sensitivity of closely proximate components. Additionally, a soldered connection may break down as a result of the operating conditions encountered in particular applications. Nut and bolt connections can come loose and are difficult to use in close quarters. While crimping devices generally have sufficient physical strength, they too are not generally reusable. Therefore, there is a recognized need for a reusable connecting device which can provide high electrical conductivity as well as a strong physical connection with another object, especially in environments over 200° C. and under high vibration conditions.
  • heat recoverable metals have been used in reusable connecting devices such as those disclosed in U.S. Pat. Nos. 4,022,519 ('519) and 3,740,839 ('839) the disclosures of which are both incorporated herein by reference.
  • heat recoverable metals are usable for connecting devices. Basically, these heat recoverable metals are alloys which exhibit the shape memory effect.
  • An article made from heat recoverable metal can be reversibly deformed after being cooled to near or below its martensitic transition temperature M s (the temperature at which transformation begins).
  • the heat recoverable metal recovers toward its original configuration.
  • a s the temperature at which the metal starts to revert back to austenite
  • the recovery ends at A f the temperature at which the transition to austenite is complete).
  • the device of '839 is a reusable connecting device which utilizes a heat recoverable metallic band disposed about a resilient member, such as the tines of a forked member.
  • the tines are spaced from one another so that they can be moved inwardly, but when so moved, exert an outward force.
  • the band is warmed to a temperature sufficient to cause the metal to transform to its austenitic phase.
  • the band then shrinks with a force sufficient to overcome the opposing force of the tines, such that the tines are moved inwardly, toward one another to contact and hold an object between them.
  • the device is reusable in that when the temperature of the band is lowered sufficiently to cause the metal to transform to its martensitic phase, the opposing force of the tines overcomes the yield strength of the band, thereby outwardly expanding the band and allowing the object placed between the tines to be released.
  • the device of '519 also discloses a reusable connector.
  • the connector includes a heat recoverable metallic band disposed about a non-resilient, deformable member, typically a hollow cylinder that has been slotted to form tines.
  • the band is lowered to a temperature sufficient to cause the metal to transform to its martensitic phase.
  • the object is inserted between the tines, forcing the tines and consequently the band in its martensitic phase to be expanded outwardly.
  • the band is warmed to a temperature sufficient to cause the metal to transform to its austenitic phase.
  • the band contracts and drives the tines towards their original configuration, thereby engaging the object.
  • the connector is reusable in that upon lowering the temperature of the band sufficient to cause a martensitic phase transformation of the metal, the band relaxes sufficiently to allow the object to be removed from the connector by deforming the deformable member.
  • the device of the instant invention is capable of creating a contact force with a substrate regardless of the temperature and hence phase of the heat recoverable metal, sufficient to provide a physical connection and preferred electrical continuity to the connection.
  • the instant invention accomplishes the above through the use of resiliently deformable tines which grip a substrate with sufficient force to provide a physical connection which in the case of conductive tines provides electrical continuity, regardless of the temperature and hence phase of a heat recoverable metal band defining a driver member which surrounds the tines.
  • the driver member begins to contract and above the A f temperature it has contracted sufficiently to supplement the force of the tines against the substrate.
  • a resiliently deformable socket member having at least two permanently, inwardly biased tines capable, in the case of conductive tines, of independently electrically contacting and holding a substrate and a band of heat recoverable metal defining a driver member surrounding the tines.
  • the driver member As the driver member is warmed through its A s temperature, it recovers and contracts, thereby supplementing the force of the tines in contact with the substrate.
  • the driver member relaxes and the tines of the socket member alone hold the substrate. The substrate may then be removed from the tines.
  • the driver member is warmed again through its A s temperature, the driver member again contracts, thereby supplementing the force of the tines and securely connecting the substrate and the device sufficient to enable the connection to be maintained at high temperature and high vibration.
  • the instant invention provides and maintains relatively high electrical conductivity connection at relatively high temperatures, e.g. up to 260° C.
  • relatively high temperatures e.g. up to 260° C.
  • the driver member was made from a nickel/titanium/copper alloy
  • the electrical conductivity of the connection was measured at 32% at 260° C.
  • the force of the connection has proven to be stable for over 1000 hours.
  • the driver member is made from a recently developed family of alloys disclosed in copending and commonly assigned U.S. application Ser. No. 355,274 which is incorporated herein by reference.
  • the preferred alloy has an M s temperature of 70° C. at an applied stress of 20,000 psi and an A s temperature of 50° C.
  • the driver member fits loosely around the socket member.
  • the driver member contracts driving the tines into engagement with the substrate.
  • the driver member is cooled through its M s temperature, e.g., by the cessation of operation of an airplane engine, the driver member relaxes and the substrate may be removed.
  • the tines include a distal end defining an annular groove in which the driver member is located. Since, during the martensitic phase the driver member fits loosely around the tines, it is advantageous to securely locate the driver member on the socket member.
  • FIG. 1 is a partially cross-sectioned perspective view illustrating the preferred embodiment of the heat recoverable supplementary force connecting device in accordance with this invention.
  • FIG. 2 is a partially cross-sectioned view of the device of FIG. 1.
  • FIG. 3 illustrates in schematic form, a mating pin inserted in the connecting device of the instant invention before heat recovery.
  • FIG. 4 illustrates in schematic form, the connecting device of FIG. 3 after heat recovery.
  • a heat recoverable supplementary force connecting device generally indicated by the numeral 10.
  • the device includes a socket member 12 and a band of heat recoverable metal defining a driver member 14.
  • the socket member 12 is resiliently deformable and electrically conductive.
  • the socket member is made from copper alloy and it is preferably made from alloy 7021*.
  • the socket member 12 includes a at least two fork members defining tines 18.
  • the tines 18 have an unstrained configuration from which at least one of them may be resiliently deformed away from the other to define a socket for receiving and holding mating pin 22 as seen in FIGS. 3 and 4.
  • the tines are inwardly disposed beyond their original configurations such that they have a permanent inward set.
  • the inside diameter of the socket member 12 at the distal end 16 is less than the outside diameter of a substrate, such as mating pin 22 illustrated in FIGS. 3 and 4.
  • the copper alloy preferably has a tensile yield strength of 60 KSI.
  • the distal end 16 defines an annular groove 20 in which the driver member 14 is located. It is understood that it is within the scope of the invention to fabricate the socket member from a non-electrically conductive material such that the socket will still hold a substrate such as a mating pin with sufficient force to provide a physical connection.
  • the driver member 14 is a band of heat recoverable metal having a first original heat recovered phase known as the austenitic phase and a second relaxed phase in which the metal may be expanded known as the martensitic phase.
  • the driver member is capable of undergoing a transformation between the phases. Specifically, the driver member 14 may be diametrically expanded when the metal is in its martensitic phase so that the driver member 14 loosely surrounds the tines 18 of the socket member 12. When the driver member 14 is warmed to a temperature at which its metal is in the austenitic phase the driver member 14 will recover inwardly to exert a supplementary inward force on the tines 18.
  • a number of different shape memory alloys may be used for making the driver member.
  • the driver member may be made from any of the alloys described in U.S. Pat. No. 3,740,839 as well as those described in U.S. Pat. No. 3,753,700 which are both incorporated herein by reference.
  • the driver member is made from a shape memory alloy having the following composition: 49 atomic percent Ti, 41 atomic percent Ni and 10 atomic percent Cu. This composition has a M s temperature of 70° C. at an applied load of 20 KSI, and an A s temperature of 50° C. under no applied load.
  • the driver member 14 in its austenitic phase has a tensile yield strength of at least 60 KSI when made from this material.
  • the driver member is capable of spontaneous expansion as it changes to martensite. In other words, the driver 14 undergoes expansion (i.e., a spontaneous increase in diameter) as it goes to the martensitic phase without assistance from the tines 18.
  • driver member may be employed to provide multiple levels of supplementary force corresponding to the different metal transformation temperatures that may be utilized for each respective driver member.
  • the driver member 14 is placed over the tines 18. As a result of the normal elastic nature of the tines 18, they will ordinarily partially spring back. Before the driver member 14 is placed over the tines a means for holding the tines completely closed is desirable to prevent this partial spring back and to facilitate the initial placement of the driver member to its correct position around the tines 18 and in groove 20.
  • FIGS. 2-4 shows the driver member 14 as not resting on any portion of the tines 18.
  • the driver member 14 will, by force of gravity or through movement of the device, rest upon and lightly contact some portion of the tines 18. Regardless of such contact, the tines 18 can be resiliently deformed outwardly to define the socket without deforming the driver member.
  • FIGS. 3 and 4 there is shown a schematic representation of the device 10 in accordance with this invention connected to a mating pin 22, before and after heat recovery.
  • FIG. 3 illustrates the operation of the device before heat recovery and
  • FIG. 3 illustrates the operation after heat recovery.
  • tines 18 are expanded outwardly and do so without contacting the driver member 14 since the driver member fits loosely around the tines 18 in the annular groove 20.
  • FIG. 4 illustrates the device at or above the A s temperature.
  • the driver member 14 As illustrated in FIG. 4, as the driver member 14 is warmed to its austenitic temperature, the driver member 14 recovers and shrinks diametrically, increasing the force exerted by the tines on the mating pin 22. It is very difficult to remove pin 22 from the device 10 without cooling. However, cooling the driver member 14 to a temperature at which its metal is in the martensitic phase causes the diameter of the driver member 14 to increase spontaneously allowing the mating pin 22 to be removed since the only force holding it in the socket results from the inward set of the tines 18.
  • the device 10 having a proximal end 24 defining a termination area. In some applications this may prove to be quite useful for terminating cable by crimping, soldering or other appropriate methods as desired.
